FIELD: machine building.SUBSTANCE: inventions group relates to machine building, namely to the hydraulic brake systems. The hydraulic brake system contains pressing element, hydraulic oil filled actuator, and remote devices for air gap adjustment between the press element and brake work surface. The remote devices contain the hydraulic accumulator to store the specified hydraulic oil volume at minimum pressure. The brake system actuator has the brake cylinder in which the brake piston passes, that is freely installed longitudinally. The brake piston and brake cylinder limit the brake return chamber. For the press element removal from the brake work surface the return brake chamber of the brake system actuator is made with possibility of connection with the hydraulic accumulator. The hydraulic oil volume of the hydraulic accumulator determines distance between the press element and brake work surface in lowered position of the brake system such that to exclude the mechanical stop or lock devices. Method of the air gap adjustment means that for the press element removal from the brake work surface limited by the brake piston and brake cylinder the return brake chamber of the brake system actuator is connected with the hydraulic accumulator such that mentioned specified hydraulic oil volume is injected to the brake return chamber, at that the freely installed brake piston is moved, at that this movement is limited by the hydraulic oil volume only, thus distance between the press element and brake work surface in the lowered position of the brake system is determined.EFFECT: simplified design and improved reliability of the system.7 cl, 1 dwg |
